There are a lot of reasons to want to build a time machine. To learn the truth about historical places and events, to see creatures that have been extinct for millions of years, to kill Hitler – always a favorite. You could go to the Library of Alexandria and save the works of great scientists and philosophers that have been lost to history. You could document the Crucifixion or watch the fall of Rome first-hand. You could see Jimi or Elvis or Janice or Kurt in their heyday, watch the original performances of Shakespeare’s plays, or talk engineering with DaVinci. With a time machine, the whole of history is open to you, and your options are just about limitless.

All Ron Mallett wanted to do with his time machine was see his dad.

Mastering time travel is easier if you have several lifetimes.

This book is not just about how one man went about figuring out how to travel through time. That in itself would be interesting, since time travel has been a dream of mankind ever since we figured out that time was a thing. There’s a lot of complicated science that goes into not just manipulating time, but figuring out that it can be manipulated, and it takes half a lifetime to master. A lot of popular science books focus on the science, unsurprisingly, and talk about how certain things were discovered and what can be done with them in the future.

That’s all well and good, but this book adds an extra element that’s often missing from other popular science texts. It talks about why.

When Ron Mallett was ten years old, his father died of a heart attack brought about by a combination of smoking, poor dietary choices, and a genetic inclination towards heart problems. Overnight, the man that young Ron loved and idolized was gone, leaving him directionless at an age when having a father can be so very important. With the loss of a beloved parent, it’s entirely possible that Ron could have seen his life crippled from that day onward.

It might have been, if not for H.G. Wells and his famous book, The Time Machine.

After he read this book, the notion that time could be navigated became the center of his life. His first attempt at a time machine – built of pipes and wires in his basement – was unsuccessful, of course. But he was undeterred, and realized that if he was going to make this dream come true, he would have to buckle down and start learning some science. Just the idea that he might one day build a machine to travel through time was enough to give him direction and purpose, and it set him on a course that would go on to define his life.

If he manages to make this work, the UCONN Velociraptors will be unstoppable!

The book is a memoir of his own travels through the world of physics and relativity, moving from one point to another as new ideas and discoveries signposted his route towards a theory of time travel. Initially guided by Einstein, Mallett went from being a young academic to programming computers for the Air Force, to becoming a full-fledged academic at the University of Connecticut. He makes sure that the reader can not only follow all the steps that he took, but that we can also see why he took them. What chance encounters and lucky finds pushed him forward, or what unfortunate incidents slowed him down. He reminds us all throughout the book of why he has chosen to do science, and never lets us forget this motivation.

At the same time, he is sure to tell us about two rather significant obstacles to his progress. The first, of course, was that he felt he couldn’t be honest about why he was studying what he was studying – relativity, black holes, lasers, that kind of thing. For fear that he would be labeled a crackpot and denied the opportunities he would need, he revealed his ambition to build a time machine only to those he felt he could absolutely trust. As far as anyone else was concerned, of course, he was just another theoretical physicist trying to figure out how the universe worked.

The other challenge he faced was that he was African-American in a field that was very, very white at the time. He had to deal with racism in both its overt and covert forms, and work even harder to prove himself to those who couldn’t – or wouldn’t – see past his skin color. He doesn’t dwell on it in this book, since that’s not what this book is about. But I’m sure if he wanted to write about what it was like trying to break into physics academia as an African-American in the 60s and 70s, he probably could.

Ladies and gentlemen, the father of time travel.

What’s most important, though, is that he continually reminds us of why he’s doing what he’s doing. He talks about his father, and the memories he had of him. He keeps his non-academic life in view, letting us in on his personal triumphs and failures, his struggles with depression and his joys at advancing towards his goal. The end result is a book that is not only about science, but about a person. The emotional thread that runs through this book is strong, and even if you can’t quite follow the science, you can still follow the passion that Ron Mallett has for this project.

The book, while fascinating, is technically unfinished. He has yet to build his time machine, and there’s no proof that the ideas he’s come forward with will actually work, even if the math says they should. As the book finishes, he has a plan, and he lays out the way he thinks his machine should work, but we’ll have to wait to see how that works out. Whether he succeeds or fails, though, he has built up a lifetime of research that has expanded our understanding of space and time in such a way that Einstein – and Ron Mallett’s father – would no doubt be proud of.
